Filed: 1921-03-16
Abstract: 181,501. Merz & McLellan, Weeks, E. G., and Baker, H. H. March 16, 1921. Plate apparatus.- In a heat-exchanger comprising a plurality of corrugated sheets spaced apart with the corrugations parallel to one another, with means at the margins of the sheets to close the spaces between alternate pairs, thus providing two sets of through.passages at rightangles to each other, the spaces are closed on two sides by placing the edges parallel to the lengths of the corrugations of each pair in contact and securing them, preferably by rolling one-edge over the other and gripping them between the end of spacing-bars which lie between each pair of sheets along their transverse margins. The rectangular spacing-bars 11 are rolled to fit the corrugations and constitute means for closing the other set of spaces, are preferably bifurcated at their ends 13 and are secured together by bolts 15, the adjacent portions of the bars gripping the rolled edges 12 of the sheets 10. Bolts 14 secure the sheets to the bars, and joints are made by rolling the meeting edges one over the other and bolting through the rolled portions and spacing bars.

Title: Self-priming centrifugal pump
IPC: F04D9/02
Filed: 1962-03-05
Abstract: 948,553. Centrifugal pumps. G. G. TURNER. (Barnes Manufacturing Co.). March 5, 1962, No. 8347/62. Heading F1C. The self-priming centrifugal pump shown in Fig. 3 comprises a volute 26 which may be carried by the cover plate 12 of the pump casing 10. As shown in Fig. 2, the volute 26 extends around the whole periphery of the impeller 14 and is extended beyond the cutwater 25 as a diffuser discharging at 27 into the upper part of the casing 10. An inlet manifold 20 carrying a wear ring 22 embraces a boss 18 which supports a shaft seal 19, and extends upwardly to meet an inlet connection (not shown) coaxial with a discharge connection 29 but located at the opposite side wall of the casing 10. A priming passage 31 opens into the lower part of the volute 26 at 30, the opening 30 being located between 180 degrees and 270 degrees from the cutwater 25 in the direction of impeller rotation. Preferably, the axis of the passage 31 is substantially vertical and intersects the outer wall of the volute 26 at a point located 30 degrees counterclockwise from a vertical plane through the impeller axis. The passage 31 is preferably of conical form, converging towards the opening 30 at an angle B of 6 to 8 degrees, the length L being such that the cross-sectional area of the passage at the level 6-6 is 1À49 to 1À63 times that at the level 5-5, the latter area being approximately equal to that of a circle whose diameter is equal to the width of the impeller blades. Preferably, the inlet to passage 31 is cut back at an angle E of 30 degrees. Initially, the casing 10 is filled with liquid through an opening 11 closed by a filling plug. Thereafter, sufficient liquid is retained in the casing 10 after each operation of the pump to ensure priming when the pump is started again. During priming, liquid is discharged at 27 into the upper part of the casing 10, where air or gas entrained in the liquid separates from the liquid and is discharged through the outlet connection 29, the liquid returning to the lower part of the casing and then travelling up the priming passage 31 to be recirculated, this cycle being repeated until the inlet manifold 20 is purged of air or gas. After completion of priming, the passage 31 acts as an additional discharge diffuser through which flows about 25% of the total discharge. The bottom wall of the casing 10 may be provided with a protuberance immediately below the passage 31, acting as a baffle to direct the flow into or out of the passage. The impeller may be fully shrouded, the wear ring 22 then being omitted.

Abstract: 1,217,005. Polyether polyols containing ester groups. WITCO CHEMICAL CO. Inc. 21 Feb., 1968. [28 Feb., 1967], No. 8384/68. Heading C3R. Ester-containing polyether polyols useful for making polyurethanes are obtained by reacting a polyoxyalkylene compound, containing at least 2 OH groups and having a molecular weight of 600 to 5000, with a polycarboxylic acid cyclic anhydride in a molar ratio of 1:1 to 1:15 respectively, and reacting the resulting polyester with a 1,2-epoxide, the molar ratio of epoxide to anhydride being not less than 1:1. The preferred polyethers are propylene oxide adducts of glycerol containing 20 to 50 mols of oxide per mol of glycerol. Other alkylene oxide adducts of polyhydric alcohols may be used as well as polyethylene-, polypropylene-, polybutylene- and polyethylene-propylene glycols. Suitable anhydrides are phthalic, maleic, succinic, aconitic, chlorendic, glutaric and chlorinated phthalic anhydrides and the dianhydride of benzene tetracarboxylic acid. After the reaction with the epoxide, the polymer is preferably neutralized, e.g. with HCl. It is possible to react all three components simultaneously, but conditions must be such that chains of anhydride-epoxide products are not predominantly formed. In making polyurethane foams, polymers of molecular weight 2000 to 4000 are prepared for flexible foams. For rigid or semi-rigid foams, the molecular weights are preferably 1000 to 2000. Conventional procedures are employed.

Abstract: 756,598. Briquetting ores; iron manufacture. VOGOGAS SOC. ANON. March 25, 1954 [Jan. 16, 1954], No. 8794/54. Classes 72 and 82(1). A method of treating briquettes containing ore, carbon and a binding agent which softens on heating comprises charging the briquettes through a hopper at the top of a low shaft furnace into a zone in which they are rapidly heated to 150‹-250‹C. and are supported in such a manner that they are relieved from pressure from above, passing the heated briquettes into a reducing zone, and discharging the reduced metal and slag through tap holes at the bottom of the furnace. As shown, briquettes containing 70 parts iron ore, 30 parts carbon which may be coal, and 8 parts pitch are charged into a hopper 2 of a low shaft furnace 1 from which they slide down cones 3 and at the same time are subjected to a blast of hot gas, e.g. coke oven gas cooled to 250‹C., which rapidly heats the briquettes and causes a hard skin to be formed thereon. The briquettes then fall into the reducing space where the carbon is gasified and the ore reduced by hot air from nozzles 4, the reduced iron being removed through a tap-hole 5 and the slag through a tap-hole 6.

Title: Improvements relating to the treatment of petroleum oils
IPC: C10G29/20
Filed: 1925-04-03
Abstract: 254,784. Marks, E. C. R., (Solar Refining Co.). April 3, 1925. Mineral oils, extracting; alcohol, dehydrating. -Petroleum from which the gasolene and kerosene have been removed is separated into lubricating and other fractions by continuous extraction with alcohol, preferably anhydrous. In the apparatus shown, oil flows from a pipe 12 abound baffles in a tank 1 while alcohol is admitted from a tank 7 by pipes 11, 17, 15. and perforated coils, a temperature of about 15()--170‹ F. being main. tained by closed steam coils. The extract overflows through a pipe 3 to a settling tank 2 for undissolved oil, and on to a still for removing the alcohol to a condenser 6 and the storage tank 7. The alcohol is dehydrated in a chamber 8 of the tank 7 by dehydrated copper sulphate or other hygroscopic material contained in bags, and is returned to the tank 1. The extracted oil is removed through a pipe 22. When say 35 per cent of cracking stock or any other desired fraction has been removed, the treated oil is run through an outlet 16 to a second similar extraction apparatus and there treated until say 10 per cent of light lubricating oil has been extracted. It is then passed to a third apparatus in which sav 35 per cent of lubricating stock is extracted, and into a fourth where say 10 per cent of heavy lubricating oil is removed. The residual 10 per cent. especially if of an asphaltic nature, may be used as a binder. It is preferably blown to increase its consistency. The extracted oils are freed from paraffin by chilling, from alcohol by heating, and from other impurities by steam or acid or acid-clay treatment. The flow of oil through the extraction units mav be continuous if the quantity and the rate of distillation of the alcohol in each unit be suitably adjusted. The crude red oil stock extracted by the third apparatus may be treated in a supplementary apparatus with alcohol at about 150‹ F. to dissolve out lighter oil and so increase its viscosity. The alcohol may be made anhydrous Initially by treatment first with lime and then with dehydrated copper sulphate.

Title: Manufacture of flexible reinforced tubes
IPC: B29C48/13
Filed: 1976-03-05
Abstract: 1510598 Flexible reinforced tubes DAYCO CORP 5 March 1976 [5 March 1975 (3)] 08967/76 Heading F2P A method of forming a flexible helically reinforced tubular conduit comprises, disposing a plurality of rigid mandrels 22 in endto end relationship to form a mandrel assembly, moving said mandrel assembly through a fabrication station 23, thereby passing a helical coil of wire about each mandrel and then passing the assembly and coil through an extruder head 36 of extrusion apparatus 35 at a speed correlated with the speed of forming of the coil and extruding a tube of plastics material over the coil and mandrel assembly to form said conduit, and thereafter, on exiting from the frabrication station, separating the conduit from each of the mandrels. As shown two wires 26 covered with a plastics material are wound around the mandrels to form coils 33. After the plastics outer cover is formed over the coils, whereupon it bonds to the plastics of the wires, the mandrels and conduit pass through a cooling chamber 37. To separate the conduit from the mandrels there is a severing means 41 for dividing up the mandrels and associated conduit and removing means 42 for removing the conduit from each mandrel. Means 41 consists of a cutter 50 and a heater 51. The cutter cuts the coils axially where adjacent mandrels abut. Heater 51 then softens the plastics covering in the same area. Adjacent mandrels are then pulled apart thus tearing the plastics covering. This is achieved by puller 52 moving the downstream mandrel at a quicker rate than the adjacent mandrel. The mandrel and conduit is then moved to conveyer 62 by conveyers 61. Then it is moved into supports 68 of means 42. The removing means grasps the end of the conduit and holds it stationary. A rod of this means connects with the mandrel and moves it axially whilst rotating it in a direction opposite to the hand of the coils 33. This rotation expands the conduit slightly and facilitates removal of the mandrel. The mandrel is then passed via conveyer 74 to roller assemblies 75 and belt conveyer 76. A lateral transfer apparatus 77 feeds the mandrels to a start position where they are fed serially on to belt 95 and thence to belt 24 for reuse. The conduit is dispensed from supports 68 and proceeds to a further operation.

Title: Improvements in thermal responsive electric switches of the glow discharge type
IPC: H05B41/08
Filed: 1947-04-03
Abstract: 644,998. Thermal switches. BRITISH THOMSON-HOUSTON CO., Ltd., and SCOTT, W. J. April 3, 1947, No. 9084. [Class 38 (v)] [Also in Group XIII] In a glow-discharge switch use is made of the effect of the local flow of heat in the bimetallic element or elements (see Group XIII) to prolong the period in which the contacts are closed. In Fig. 2 a U-shaped bimetallic strip 5 has its longer limb secured to a support 6 of good heat conductivity. When the glow discharge heats the element it distorts into the position shown by dotted lines 10 to close contacts 8, 4. Due to the more rapid loss of heat from the longer limb than from the shorter limb 7 when the discharge ceases, the former tends to return to its original position first and by so doing, prevents the immediate re-opening of the contacts. Fig. 4 and Figs. 5-7 (not shown) illustrate modifications in. which the shorter limb 12 of a U-shaped element is fixed to the support, the " U " being formed by cutting rather than bending a bimetal strip into that shape. In other modifications the bimetallic element may be formed by twisting a strip through 180 degrees near its supported end, Fig. 8 (and Fig. 9, not shown), or by welding the ends of two bimetallic strips together so that the two portions of the element tend to deflect in opposite directions. The two strips may be of different pairs of metals or of different thicknesses. Two co-operating bimetallic elements similar in shape to the element of Fig. 2 may also be used, Figs. 12, 13 (not shown). Specification 537, 901, [Group XL], is referred to.
